Rotary compressor

A horizontal type rotary compressor comprising:

• a hermetic casing with bottom portion thereof defining a lubricant reservoir;
• a motor part comprising a stator fixedly disposed on the inner wall of said hermetic casing;
• a rotor rotatably arranged in a spaced and concentric relationship with said stator, and
• a rotational shaft connected with said rotor and extending horizontally along said hermetic casing;
• a compressor part connected to said motor part by means of said rotational shaft and comprising
• an eccentric member integrally formed with said rotational shaft at the opposite end from said motor, bearing members provided at both sides of said eccentric member for supporting the rotational movement of said shaft, said bearing members having a suction aperture and a discharge aperture in communication with said lubricant reservoir for allowing lubricant to pass therethrough, said discharge aperture having a first diameter,
• an annular member concentrically and rotatably surrounding said eccentric member and placed between said bearing members,
• a cylinder for defining a compression chamber together with said annular member and said set of bearing members,
• a blade extending radially through said cylinder, having one end in contact with said annular member and another end urged by a spring member, said blade dividing said compression chamber into a high pressure compartment and a low pressure compartment;
• and
• a pipe member having a second internal diameter larger than said first diameter, said pipe member further having one end in communication with said discharge aperture of one of said bearing members, but being spaced therefrom to define an opening therebetween, and another end in communication with a lubricant path leading to where machine contacts exist, wherein
• said blade and said bearings define a blade chamber whereby said blade due to the reciprocal movement thereof sucks lubricant through said suction aperture into said blade chamber and discharges lubricant from said blade chamber through said discharge aperture into said lubricant pipe member and as lubricant passes through said opening it induces ambient lubricant into said pipe thereby supplying lubricant to said lubricant path while substantially prohibiting the reverse flow of lubricant back into said blade chamber.
